 Ode does it matter where you buy it from? Amazon has them pretty cheap

RE: CS>TDS meter

[abeland1]

May I suggest that you purchase an EC meter? They are still less than $20 from 
eBay. If you're lucky, you'll get one that will have reasonably accurate 
absolute measurements at 50 PPM, plus or -10%. Discounting the absolute 
measurements, it will give you an indication of what's happening from one batch 
to the next.
As far as the particle size is concerned, color or the lack of is the key. That 
can be subjective and is best observed with a white surround.
The TDS meter is calibrated for sodium atoms. The meters came about as 
something the Chinese can sell to people with saltwater aquariums. For quite a 
while, that was all that was available. We found that if we multiply the TDS 
reading by two, we can have a pretty close reading for silver ions. When the 
manufacturers caught on to what we were using them for, they made them so that 
they also had a button to read electrical conductivity in microsiemens. All 
they're doing is multiplying the TDS reading by two. A lot of sellers of 
colloidal silver generators were sorry to see these become available. They were 
able to claim any PPM figure they wanted and tell people that to measure PPM, 
they would have to send their CS to a lab. Oh yes, and the labs did not know 
what they were doing, of course.
How's the color going?

My first TDS meter just arrived.  It talks about calibration but with no 
directions as how to do this.  Since it is showing 862ppm and it has not been 
dipped into anything I am anticipating that this needs to be done.
Would someone point me in the right direction? I've searched but have not found 
good directions.
